Product Description

Basic Freewheels FBO
for assembly with connecting parts
with sprags, available in five types
 
Features
Basic Freewheels FBO are sprag freewheels with ball bearings to be assembled with customer connecting parts. The freewheels are particularly suitable for installation in housings with oil lubrication and seals. The freewheels FBO are used as:
 Backstops
 Overrrunning Clutches
 Indexing Freewheels
In addition to the standard type, four other types are available for extended service life and
indexing accuracy. Nominal torques up to 160 000 Nm. Bores up to 300 mm. Many standard bores are available.

The maximum transmissible torque is 2 times the specified nominal torque.
The specified maximum speeds apply for installation conditions as given with Complete Freewheels. Knowing the actual installation conditions higher speeds can be permitted under some circumstances.

Application example
Basic Freewheel FBO 127 SF as an overrunning clutch between the creep drive and the main
drive of a cement mixer. In the case of creep operation, the outer ring is driven by the shaft
coupling. The freewheel works in driving oper - ation and drives the unit at a low speed via the
main gearbox. In normal operation (freewheel - ing operation), the inner ring overruns and the
creep drive is automatically disengaged. The freewheel is connected to the oil lubrication of
the main gearbox and does not require any special maintenance. The arrangement of the
seals between the freewheel and the main gear box is advantageous. In normal operation
(freewheeling operation), this is at a standstill and hence generates no additional frictionrelated temperature rise.
 
Mounting
The customer connecting parts are centered on the ball bearing external diameter F and
assembled via the outer ring. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter F of the connecting part must be ISO H7 or J7. The centering depth C must be observed.
Lubrication
An oil lubrication of the specified quality must be provided.
